Is Encapsulated Power Diode Needed to Install Redarc Tow-Pro Liberty on a 2020 Subaru Forester

Question

Question:

I‘m installing the RedArc TowPro Liberty on a Subaru Forester 2020 and am wondering if it requires the diode #RED34FR to stop the brake light signal feed back? In the install video for the 2020 Outback you‘re just tapping into the signal from brake pedal switch nothing mention of a diode anywhere. Essentially it’s the same vehicle platform as the Forester… both come with standard features Adaptive Cruise Control, AEB, etc. How come that the diode is mentioned nowhere? Yet when you search the questions it’s basically referenced as a must have to protect your electronics. Do we need it on those newer Subarus or not?? Could you please clarify! Thank You!

The Redarc Encapsulated Power Diode # RED34FR shouldn't be needed for installing the Redarc Tow-Pro Liberty # RED24FR and Pigtail # RED69FR on your 2020 Subaru Forester.

The answer page you're referring to didn't have us telling someone to install it, rather that person asked how it installs and our expert gave them insight on how to install it. Aside from that we haven't recommended the Power Diode for any other Subaru vehicles.

@Aldo I wasn't able to find any specifics on your 2022 Mitsubishi Triton, but I did reach out to my contact at Redarc and they said it is used when a vehicle has driver aids like Advanced Safety Systems e.g. Adaptive Cruise Control, Assisted Emergency Braking, or Autonomous Emergency Braking sort of things. If your Triton has those then you'll likely need the Encapsulated Power Diode # RED34FR, but they don't have a specific fit list or anything prior to purchasing.

Since you said you do not have a towing package on your 2015 Highlander, you will first need to start with a 4-way wiring harness like part #118449. This harness simply plugs into the connection points located in the rear cargo area as shown in the…

Hey Paul! Does your 2025 Toyota 4Runner have the factory tow package? If it does, there is a brake controller port you can use for plug and play installation. If you're using the Tekonsha POD #TK92UR you got before then you need the Tekonsha…

While I can sympathize with your issue, it is not safe to tow a trailer if you only have a 2" hitch ball and your trailer coupler is designed for a 2-5/16" hitch ball, even for a short distance; the insecure connection between hitch ball…

Hello John, thanks for reaching out. Does your 2025 4Runner already have a 7-way plug installed on the back? If no, you will need the #ETBC7 kit in order to use a brake controller. If you already have a 7-way you should already be prepped for a brake…

This is a common problem that I have seen when using the factory connector on your 2019 Toyota 4Runner. The ground wire for the brake controller is not capable of supporting the negative power from the Redarc Tow-Pro Elite #RED44FR. Redarc has their…

Honestly, Joah, if I were you I would try to find a shop in your area that has a heavy-duty torque wrench and breaker bar. 450 ft/lbs is quite a bit and most typical torque wrenches don't got that high. Sometimes if you can find a shop that has…

The CIPA Custom Towing Mirror #CM11401 that you're looking at is a fit for a Ram pickup. Since you have a 2021 Toyota Tacoma you'll need to look at a universal mount towing mirror as I still have yet to hear of a custom mirror made for a…
